SMBv1 error file share not secure


In Windows 10 Fall Creators Update and Windows Server, version 1709 (RS3), the Server Message Block version 1 (SMBv1) network protocol is no longer installed by default.

We spotted this recently at one of our customer’s site whereby a logon script was no longer mapping a particular network drive to an old NAS device and coming up with the following error;

You can’t connect to the file share because it’s not secure. This share requires the obsolete SMB1 protocol, which is unsafe and could expose your system to attack.

How to enable SMBv1

Microsoft have removed this feature for security reasons as SMBv1 is not very secure but if you do however need to enable access to older devices then you can enable the feature by doing the following;

Go to Control Panel > Programs and Features > Turn Windows Features on or off > check or uncheck the box for “SMB 1.0/CIFS File Sharing Support”

Number of Exchange Accounts Limit in Outlook

By default the number of Exchange Accounts Limit in Outlook 2010 and Outlook 2013 is set at 10 Exchange accounts for a single Outlook mail profile.

In most cases this is sufficient although we have had a few customers ask us to increase the number of Exchange Accounts limit in Outlook in the past.  This could be for many reasons, for example some Directors of companies may want to see all the departmental mailboxes (sales@, info@) as well as their staff mailboxes in order to keep track of what is being sent in and out from their company.

Anyway the Exchange Accounts Limit in Outlook can easily be fixed by making the following change in the Windows Registry, please see below;


How to Increase the number of Exchange Accounts limit in Outlook

To increase the limit to up to 9999 Exchange accounts, the following Registry value needs to be created.

Key: HKEY_CURRENT_USER\Software\Microsoft\Exchange
Value name: maxnumexchange
Value type: REG_DWORD

Here is step by step instructions on how to open the Windows registry and to make the relevant changes;

  • Click the Start button which is located on the bottom left of your screen.
  • In the Start Menu, type regedit and press Enter.
  • If prompted by User Account Control, click Yes to open the Registry Editor.
  • The Windows Registry Editor window should open and it will look similar to the example shown below.

Number of Exchange Accounts Limit in Outlook

  • Then Navigate your way through to HKEY_CURRENT_USER, SOFTWARE, MICROSOFT and EXCHANGE
  • On the Edit menu, point to New, and then select DWORD Value.
  • Enter MaxNumExchange, and then press the Enter key.
  • In the Details pane, press and hold (or right-click) MaxNumExchange, and then select Modify.
  • In the Value data box, enter the required value, and then select OK.

As with all Registry changes a reboot will be required to take effect.

Disable Programmatic Access in Outlook

Programmatic Access in OutlookWe had a customer log a call today as they where using an application which sends an invoice email message to their customers. The application did this through Outlook however for each email they sent out they got the following warning message about Programmatic Access in Outlook:

A program is trying to send an e-mail message on your behalf. If this is unexpected, click Deny and verify your antivirus software is up-to-date.

They wanted this turned off but when I went to Programmatic Access in Outlook by going into Tools, Trust Center (Outlook 2007) or File, Options, Trust Center (Outlook 2010 and up) and then into the Programmatic Access section I noticed that it was greyed out and therefore it appeared that it could not be turned off.

After a bit of research I found that you can indeed turn off Programmatic Access in Outlook with the work around below but be warned that this reduces the security level in Outlook and could leave you at risk so we recommend that you use up-to-date antivirus software.

To disable Programmatic Access in Outlook you need to do the following;

  • Bring up the start menu and type Outlook
  • Right click on the Outlook icon and choose run as administrator
  • After Outlook loads, go to Tools, Trust Center (Outlook 2007) or File, Options, Trust Center (Outlook 2010 and up) and you will now be able to change the Programmatic Access setting.
